Inventor: YUMIBA MASAHIRO
IPC: H04J13/00
Filed: 2000-05-26
Abstract: PROBLEM TO BE SOLVED: To form an optimum zone in an area that can be a dead zone. SOLUTION: The mobile communication system is provided with a supplementary base station 40 that forms a zone 41 to cover a dead area 51 outside the wireless zones 11, 21, 31 of peripheral base stations 10, 20, 30. Each peripheral base station controls transmission power of an outgoing signal based on traffic to cover the wireless zone. The supplementary base station decides outgoing transmission power of its own station depending on a reception level of the signal coming from the peripheral base stations. Thus, the zone formed by the supplementary base station changes with a radio propergation state of a zone formed by the peripheral base stations. That is, when the zone of the peripheral base stations is substantially enlarged so that the dead area is decreased, the zone of the supplementary base station is controlled to be small or toward stopping the transmission of the base stations. When the dead area is increased, by controlling the zone of the supplementary base station so as to increase can always form an optimum zone.
